Few issues are more emotional, and therefore vulnerable to bad analysis, than urban crime risk. Solid research indicates that more compact and mixed development tends to increase neighborhood security. Jane Jacobs was right!

Gondolas as transit aren't exactly prevalent in the U.S., but now the concept has been put forward once again in San Diego. Jennifer Van Grove writes, "More recognizable as a ski lift or gondola, an aerial cableway system is the best answer to the airport's in-and-out transportation woes, according to County Supervisor Ron Roberts. His office commissioned a report to study the feasibility of using a so-called 'skyway' to get people from the Convention Center to San Diego International Airport, and vice versa, with a handful of stops at various points along Harbor Drive."

The study follows an environmental review conducted by the airport on a proposed $3 billion redevelopment that has prompted some traffic concerns. "The report found that a skyway system that follows Harbor Drive from Fifth Avenue at the Convention Center to the airport would cost from $230 million to $300 million to build, and an additional $11 million to $12 million to operate annually. It could transport up to 2,400 passengers per hour, per direction in enclosed eight- to 12-passenger cabins."

For the time being, Van Grove says, the idea is just food for thought. But it's been shared with the mayor, the Port of San Diego, and the San Diego Regional Airport Authority with the intent to spur interest.
